It was formed 6,000 years ago when sea levels were higher; it is isolated, rather shallow {{convert|7.5|m}}, meromictic, a few hundred meters in diameter and has extremely salty water. It has the highest recorded concentration of dimethyl sulfide in any natural body of water.<ref name=nn>{{cite web|url=http://www.nature.com/news/2011/110328/full/news.2011.188.html|title='Virus-eater' discovered in Antarctic lake|date=28 March 2011|work=Nature News}}</ref><ref>{{Cite journal | volume = 38 | issue = 3 | pages = 409–417 | last = Franzmann | first = PD |author2=PP Deprez |author3=HR Burton |author4=J van den Hoff |name-list-style=amp | title = Limnology of Organic Lake, Antarctica, a meromictic lake that contains high concentrations of dimethyl sulfide | journal = Marine and Freshwater Research | date = 1987-01-01 | url = http://www.publish.csiro.au/paper/MF9870409 |doi=10.1071/MF9870409 | url-access = subscription }}</ref>
In 2011, a new species of virophage (a satellite virus that impairs the ability of its co-infective host virus to replicate) was discovered in Organic Lake, the Organic Lake virophage. It is a parasite of 'Organic Lake phycodnavirus',<ref name=nn/> a large virus that infects algae and belongs to the nucleocytoplasmic large DNA viruses (NCLDV), but in fact may rather be a member of an extended family Mimiviridae (aka Megaviridae) than of the family Phycodnaviridae.<ref>{{cite journal |last1=Koonin |first1=Eugene V. |last2=Krupovic |first2=Mart |last3=Yutin |first3=Natalya |name-list-style=amp |title=Evolution of double-stranded DNA viruses of eukaryotes: from bacteriophages to transposons to giant viruses |journal=Annals of the New York Academy of Sciences |date=April 2015 |volume=1341 |issue=1 |pages=10–24 |doi=10.1111/nyas.12728|pmc=4405056 |pmid=25727355 |bibcode=2015NYASA1341...10K }} (Figure 3)</ref><ref>{{cite journal |last1=Maruyama |first1=Fumito |last2=Ueki |first2=Shoko |name-list-style=amp |title=Evolution and phylogeny of large DNA viruses, Mimiviridae and Phycodnaviridae including newly characterized ''Heterosigma akashiwo'' virus |journal=Frontiers in Microbiology |date=30 November 2016 |volume=7 |page=1942 |doi=10.3389/fmicb.2016.01942|pmc=5127864 |pmid=27965659 |doi-access=free }}</ref><ref>{{cite journal |last1=Zhang |first1=Weijia |last2=Zhou |first2=Jinglie |last3=Liu |first3=Taigang |last4=Yu |first4=Yongxin |last5=Pan |first5=Yingjie |last6=Yan |first6=Shuling |last7=Wang |first7=Yongjie |name-list-style=amp |title=Four novel algal virus genomes discovered from Yellowstone Lake metagenomes |journal=Scientific Reports |date=13 October 2015 |volume=5 |issue=1 |article-number=15131 |doi=10.1038/srep15131|pmc=4602308 |pmid=26459929 |bibcode=2015NatSR...515131Z }}</ref><ref>{{cite journal |last1=Schulz |first1=Frederik |last2=Yutin |first2=Natalya |last3=Ivanova |first3=Natalia N. |last4=Ortega |first4=Davi R. |last5=Lee |first5=Tae Kwon |last6=Vierheilig |first6=Julia |last7=Daims |first7=Holger |last8=Horn |first8=Matthias |last9=Wagner |first9=Michael |last10=Jensen |first10=Grant J. |last11=Kyrpides |first11=Nikos C. |last12=Koonin |first12=Eugene V. |last13=Woyke |first13=Tanja |name-list-style=amp |title=Giant viruses with an expanded complement of translation system components |journal=Science |date=6 April 2017 |volume=356 |issue=6333 |pages=82–85 |doi=10.1126/science.aal4657 |pmid=28386012|bibcode=2017Sci...356...82S |doi-access=free }} (especially Fig. 2)</ref>
